The block diagram which shows the structure of the heating cooker which concerns on Embodiment 1 of this invention. The front view of a display part which shows the example of a display of the display part which concerns on Embodiment 1

  A heating cooker according to an aspect of the present invention includes a heating unit that heats an object to be heated, an operation unit that sets an operation of the heating unit, and a display unit that displays a setting state of the heating unit set by the operation unit And comprising. The operation unit includes a first setting unit that sets a first setting, and a second setting unit that sets a second setting. The display unit displays the first setting state, which is the setting state of the first setting when the first setting unit is operated, and the second setting unit when the second setting unit is operated. The second setting state, which is the setting state, is displayed, and the display of the first setting state and the display of the second setting state are switched in the same area of the display unit. The display unit displays the second setting state when the first setting unit is operated while the display unit displays the second setting state. Switching to the display, the operation unit changes the first setting state in response to an operation on the first setting unit while the first setting state is displayed on the display unit. Furthermore, the display unit displays the first setting state when the second setting unit is operated while the display unit is displaying the first setting state. Switching to the display, the operation unit changes the second setting state in response to an operation on the second setting unit while the second setting state is displayed on the display unit. According to the heating cooker which concerns on the 1st aspect of this invention, it can cook by heating to-be-heated objects, such as a cooked item or a container containing a cooking item.

  In the said aspect, the setting part (a 1st setting part or a 2nd setting part) corresponding to the setting state which a user desires to change among a 1st setting state and a 2nd setting state is used. When the user operates, the display content on the display unit is switched to the display content of the setting state selected by the user. That is, the display unit switches to the display of the first setting state when operating the first setting unit, and switches to the display of the second setting state when operating the second setting unit. If the user again operates the same setting unit thereafter, the setting state currently selected by the user is changed when this operation is performed. Therefore, by operating only the setting unit corresponding to the setting state that the user wants to set, the display on the display unit can be switched to the display of the desired setting state, and the setting state is continuously changed. Can change. That is, the operation area is not moved during the operation, and the user can easily change the setting of the cooking device by the operation that is continued. Further, the user can operate the cooking device while checking the display of the current operation state by looking at the same area on the display unit.

  Further, in this aspect, the display of the first setting state and the display of the second setting state are performed by switching in the same area in the display unit (for example, it can be realized by using one numeric display element or the like). Thus, the heating cooker is configured. Therefore, the configuration of the display unit according to this aspect can be simplified as compared with the conventional case in which the display unit is provided with a plurality of display areas respectively corresponding to the first setting state and the second setting state. In addition, by consolidating areas for displaying information such as numeric display information (for example, temperature setting display, timer setting display, etc.) of the first and second setting states, the operation unit and the entire display unit can be combined. The occupied area can be reduced, and the size of the entire operation unit and display unit can be reduced. The “same area” substantially includes a case where the display of the first setting state and the display of the second setting state are switched in substantially the same area.

  In the cooking device according to this aspect, when the display unit displays the first setting state, when the predetermined time has elapsed since the last time the first setting unit was operated, the display unit is The display of the first setting state may be switched to the display of the second setting state. In this case, when a predetermined time has elapsed since the user last operated the first setting unit, the display unit automatically displays the second setting state in preference to the first setting state. To do. In addition, since the second setting state is displayed on the display unit with priority, the user can change the second setting state without performing an operation for switching the setting state display to the second setting state. Visible.

  The cooking device according to this aspect may further include a notification unit that notifies the operation unit that an operation has been performed. Here, the notification unit performs the first notification when an operation for changing the first setting state or the second setting state is performed on the operation unit. Accordingly, the first notification can make the user recognize that the change in the first setting state or the change in the second setting state has been received by the operation unit.

  In the heating cooker according to this aspect, the notification unit may perform the second notification when the display unit switches the display between the display of the first setting state and the display of the second setting state. . Accordingly, the second notification can make the user recognize that the setting target of the operation of the heating unit has been switched to the setting state desired by the user.

  In the heating cooker according to this aspect, each of the first setting unit and the second setting unit may be configured with a switch that has a contact point and gives an operational feeling to the user who has performed the operation. Thereby, the first setting unit and the second setting unit can recognize the operational feeling more clearly when the user presses the key with a finger or the like. For example, the user can be made aware that an operation for changing the first setting state or the second setting state has been performed. Alternatively, the user can be made aware that an operation for switching the setting target of the operation of the heating unit to the setting state desired by the user has been performed. In this case, for example, the above configuration in which the notification unit performs the second notification may be omitted. Thus, when the user operates the first or second setting unit, the setting target of the operation of the heating unit is switched to the user's desired setting state, instead of the second notification, It can be recognized by the operational feeling of the switch. For this reason, the notification by switching the display and the notification by changing the setting can be more clearly distinguished and made to be recognized by the user without increasing the notification variation based on the operation by the notification unit.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiment.

(Embodiment 1)
Hereinafter, the heating cooker of Embodiment 1 of this invention is demonstrated based on drawing. FIG. 1 is a block diagram showing a configuration of a heating cooker according to Embodiment 1 of the present invention. The heating cooker in FIG. 1 includes a heating unit 1, a notification unit 2, an operation unit 3, and a display unit 4. Here, the heating cooker further includes, for example, an insulating plate (not shown) disposed on the upper side of the heating unit 1, and the object to be heated is placed on the insulating plate by a user or the like. During the heating operation, the heating unit 1 heats the object to be heated placed on the insulating plate from below the insulating plate.

  The heating cooker is, for example, an induction heating cooker, a rice cooker, a microwave oven, a hot plate, or a toaster. The heating unit 1 includes, for example, a coil that generates electromagnetic waves for induction heating, a magnetron that generates electromagnetic waves for dielectric heating, an electric heating coil that generates heat, or an electric heater configured using nichrome wire.

  The operation unit 3 includes an operation key composed of a switch or the like, and includes a first setting unit 5 that performs a first setting and a second setting unit 6 that performs a second setting. The first setting is a setting of the control temperature of the heating unit 1, and the second setting is a setting of a cooking time, that is, a timer setting time. The operation unit 3 changes the setting related to the operation of the heating unit 1 when the user performs an operation on the first setting unit 5 or the second setting unit 6. Here, the set state includes the control temperature of the heating unit 1 and the set time of the subtraction timer for adjusting the cooking time. The display unit 4 displays the set operation state. The display unit 4 includes an LED 4c that is a numeric display element, and displays numbers indicating the control temperature, the remaining time of the cooking timer, and the like on the LED 4c by a segment display method. The alerting | reporting part 2 is comprised by a buzzer, a speaker, etc., for example. The notification unit 2 performs necessary notification to the user by generating an operation sound (for example, blowing a buzzer sound) when an operation on the operation unit 3 is performed.

  The operation unit 3 further includes a control unit 7 that controls each unit of the heating cooker including the heating unit 1, the notification unit 2, and the display unit 4 in addition to the first and second setting units 5 and 6. . The said control part 7 controls operation | movement of each part of a heating cooker based on operation with respect to the operation part 3 by a user. The control unit 7 is constituted by, for example, a CPU, MPU, or FPGA, and executes various control processes described above and in detail later based on a predetermined program. The function of the control unit 7 may be realized by cooperation of hardware and software, or may be realized only by hardware (electronic circuit).

  The control unit 7 outputs a signal indicating the start or stop of the heating operation of the heating unit 1, a signal indicating the control temperature, and the like to the heating unit 1. The heating unit 1 starts the heating operation when receiving a signal indicating the start of the heating operation, and stops the heating operation when receiving a signal indicating the stop of the heating operation. Moreover, the heating part 1 will operate | move so that the detection temperature of to-be-heated object may turn into this control temperature, if the signal which shows control temperature is received. Further, the control unit 7 outputs a signal instructing the generation of the operation sound to the notification unit 2. When the notification unit 2 receives a signal instructing generation of an operation sound, the notification unit 2 generates an operation sound. Furthermore, the control unit 7 outputs a control signal for controlling each display element (LEDs 4 a and 4 b and LED 4 c) of the display unit 4 to the display unit 4. The display unit 4 turns on or off each display element according to a control signal received from the control unit 7.

  The operation of the cooking device of FIG. 1 having the above configuration will be described below. In the heating cooker of the present embodiment, the user can start or stop the heating operation by the heating unit 1 by operating the operation unit 3. When the user operates the “OFF / ON” key 3 a of the operation unit 3, the operation unit 3 outputs a signal indicating the start of the heating operation or a signal indicating the set control temperature to the heating unit 1. When the heating unit 1 receives a signal indicating the start of the heating operation, the heating unit 1 starts the heating operation of the heating unit 1. Moreover, the heating part 1 will perform the operation | movement which changes control temperature, if the signal which shows control temperature is received during heating operation. At the same time, the display unit 4 displays a number indicating the control temperature of the heating unit 1 as a display of the first setting state of the heating unit 1 set by the operation unit 3. Moreover, the display part 4 has individually the operation | movement display element comprised by LED4a, 4b corresponding to each 1st and 2nd setting state of the heating part 1. FIG. For this reason, the user can easily visually recognize which is the set state of the heating unit 1 based on whether the LEDs 4a and 4b are turned on or off.

  In the present embodiment, the notification unit 2 performs notification as follows based on the operation of the operation unit 3. That is, when the first setting change during the display of the first setting state or the second setting change during the display of the second setting state is performed according to the operation of the operation unit 3 by the user, the notification unit 2 generates a predetermined notification sound and notifies the user that the operation unit 3 has accepted an operation on the operation key (hereinafter, this notification is referred to as “first notification”). In addition, when the setting target of the operation of the heating unit 1 is switched between the first setting and the second setting according to the operation of the operation unit 3 by the user, the notification unit 2 generates a predetermined operation sound. Then, the user is notified that the setting target has been switched (hereinafter, this notification is referred to as “second notification”). Here, the operation sound related to the first notification is composed of, for example, one sound having a length of 0.2 seconds, and the notification sound related to the second notification is, for example, the generation of a sound of 0.2 seconds. Followed by a sound that repeats twice for 0.2 seconds.

  The operation of the heating cooker when the operation of the heating unit 1 is set to the first setting state (control temperature of the heating unit 1) will be described.

  The operation unit 3 sets the start or stop of the heating operation of the heating unit 1 each time the “OFF / ON” key 3a of the operation unit 3 shown in FIG. When the “temperature up” key 5 b or the “temperature down” key 5 a as the first setting unit 5 is pressed, the operation unit 3 sets the control temperature of the heating unit 1. When the heating unit 1 is performing the heating operation, the display unit 4 displays the control temperature of the heating unit 1 on the LED 4c and lights the LED 4b. That is, the display unit 4 turns on the LEDs 4b and 4c to notify the user of the heating state during the heating operation. On the other hand, the display unit 4 turns off all the LEDs 4a, 4b, and 4c when the heating is stopped.

  The control temperature of the heating unit 1 is expressed by three numbers “1” to “9” by appropriately combining lighting and extinguishing of the three-digit seven segments of the LED 4c. In the present embodiment, the display unit 4 displays the magnitude of the control temperature of the heating unit 1 in increments of 10 ° C. in ascending order of the control temperature, “170”, “180”, “190”, to “230”, A total of nine levels of temperature are expressed and displayed by the LED 4c, such as “240” and “250” ° C. The heating unit 1 operates so that the detected temperature of the object to be heated becomes the set control temperature. The initial value of the control temperature setting temperature when the control temperature setting is switched during heating is, for example, 170 ° C.

  For example, when the “OFF / ON” key 3 a of the operation unit 3 is pressed while heating of the heating unit 1 is stopped, the operation unit 3 sets the control temperature of the heating unit 1 to an initial value of 170 ° C. At this time, as shown in FIG. 2A, the display unit 4 turns on the LED 4b to indicate that the LED 4b is in a heating operation state, and also displays a three-digit number “170” representing the current control temperature as the LED 4c. Use to display. Thereafter, when the user presses the “temperature up” key 5b twice in succession, the operation unit 3 increases the control temperature of the heating unit 1 in increments of 10 ° C. every time the “temperature up” key 5b is pressed. It changes so that it may raise only 2 times, and finally sets control temperature to "190" degreeC. At this time, as shown in FIG. 2B, the display unit 4 displays a three-digit number “190” representing the current control temperature using the LED 4c. The notification unit 2 generates an operation sound related to the first notification every time the control temperature is changed twice, and notifies the user that an operation to change the control temperature is accepted. .

  Thereby, a display area can be made small, without making it the level display which arranges LED by the number of control temperature steps. Moreover, since control temperature itself of the heating part 1 can be shown as a number using LED4c, visibility is good and, therefore, the usability of the heating cooker is improved.

  Next, when the display unit 4 displays the first setting state (the control temperature of the heating unit 1), the heating cooking in the case where the second setting (setting of the timer setting time) is performed. The operation of the device will be described.

  When the display unit 4 is displaying the first setting state, the “hour” key 6a or the “minute” key 6b as the second setting unit 6 of the operation unit 3 shown in FIG. 1 is pressed once. Then, the display unit 4 changes the display as follows. That is, the display unit 4 switches the number display indicating the first setting state to the number display indicating the second setting state on the LED 4c of three digits and seven segments. Further, the display unit 4 turns off the LED 4b and turns on the LED 4a to indicate that the number of the LED 4c indicates the second setting state. The initial value of the setting time of the subtraction timer is, for example, 0 hour 00 minutes. Therefore, the LED 4c displays a number “000” indicating the initial value, as shown in FIG.

  Subsequently, when the “hour” key 6a or the “minute” key 6b is pressed by the user, the notification unit 2 generates an operation sound for 0.2 seconds as a first notification every time these keys are pressed. To notify the user that a key operation has been accepted. The operation unit 3 changes and sets the setting time of the subtraction timer in response to each depression of these keys. Specifically, the operation unit 3 increases the set time by one hour in response to pressing of the “hour” key 6a, and increases the set time by one minute in response to pressing of the “minute” key 6b. Moreover, the display part 4 changes the content of the display by LED4c as follows according to the change of the setting time by the operation part 3. FIG. That is, when the “hour” key 6a is pressed, the display unit 4 increases the first digit from the left of the LED 4c, which is a digit representing “time”, from “0” to “9” by one, and When the “minute” key 6b is pressed, the second and third digits from the left of the LED 4c, which is a digit representing “minute”, are incremented by one from “0” to “59” as two digits. For example, when the “hour” key 6a is pressed once and the “minute” key 6b is pressed ten times, the operation unit 3 sets the set time of the subtraction timer to 1 hour and 10 minutes. At this time, as shown in FIG. 2D, the display unit 4 displays the number “110” indicating the set time (1 hour and 10 minutes) on the LED 4c. In addition, the alerting | reporting part 2 produces | generates the operation sound which concerns on a 1st alerting | reporting for every change of the preset temperature performed 11 times in total.

  When the operation for setting the set time by the user is completed, the subtraction timer starts executing the subtraction count with the set set time as a starting point. The control unit 7 controls the heating unit 1 to operate at the set control temperature until the set time of the subtraction timer is subtracted to “0”, and the remaining cooking time that is subtracted is counted. The display unit 4 is controlled to display on the LED 4c. Thereafter, when the set time of the subtraction timer reaches “0”, the control unit 7 stops the heating operation of the heating unit 1 and ends the cooking.

  In the present embodiment, the second notification for notifying that the setting target has been switched between the first setting state and the second setting state is omitted. That is, when the set control temperature which is the first setting state is displayed on the display unit 4, the “hour” key 6a or the “minute” key 6b which is the second setting unit 6 is pressed once. In the case, the notification unit 2 does not generate an operation sound as the second notification. Thereby, the operation of the notification unit 2 can be made different when the setting target is switched and when the setting value is changed without switching the setting target. Furthermore, since the notification unit 2 generates only one type of pattern operation sound as the first notification, the notification sound is simple. In the present embodiment, the keys of the first setting unit 5 and the second setting unit 6 (“temperature down” key 5a, “temperature up” key 5b, “hour” key 6a, “minute” key 6b) ) Is configured using a switch having a mechanical structure such as a tactile switch. Since the tactile switch gives an operation feeling such as a click feeling to the finger pressing the switch, the user can feel that the key has been pressed. For this reason, in the first embodiment, the second notification is omitted.

  Next, when the display unit 4 displays the second setting state (setting time of the subtraction timer), the heating cooking in the case where the first setting (setting of the control temperature of the heating unit 1) is performed. The operation of the device will be described.

  When the display unit 4 displays the second setting state, if the “temperature up” key 5b or the “temperature down” key 5a, which is the first setting unit 5, is operated once, the display unit 4 The LED 4c switches the display of the current second setting state (setting time of the subtraction timer) to the display of the first setting state (control temperature of the heating unit 1). For example, when the current control temperature of the heating unit 1 is 190 ° C., the display unit 4 switches the display content to the display of the number “190” indicating the current set temperature, as shown in FIG. Further, the display unit 4 turns off the LED 4a and turns on the LED 4b to indicate that the number indicated by the LED 4c indicates the first setting state.

  Subsequently, when the “temperature up” key 5b or the “temperature down” key 5a is pressed by the user, the notification unit 2 operates for 0.2 seconds as a first notification every time these keys are pressed. A sound is generated to notify the user that a key operation has been accepted. Further, the operation unit 3 increases the control temperature from the current set temperature to “250” ° C. in increments of 10 ° C. in response to pressing of the “temperature up” key 5b, and presses the “temperature down” key 5a. Accordingly, the control temperature is set in steps of 10 ° C. from the current set temperature to “170” ° C.

  As described above, in the present embodiment, the second notification is omitted. That is, when the set time set for the subtraction timer which is the second setting state is displayed, the “temperature up” key 5b or the “temperature down” key 5a which is the first setting unit 5 is pressed once. In the case, the notification unit 2 does not generate an operation sound as the second notification. Thereby, the operation of the notification unit 2 can be made different when the setting target is switched and when the setting value is changed without switching the setting target. Furthermore, since the notification unit 2 generates only one type of pattern operation sound as the first notification, the notification sound is simple.

  In the present embodiment, when the set time of the subtraction timer is set, the second setting state is displayed with priority over the first setting state. For this reason, when the display unit 4 displays the set control temperature, which is the first setting state, the “temperature up” key 5b or the “temperature down” key 5a, which is the first setting unit 5, is displayed. When a predetermined time (for example, 3 seconds) has elapsed since the last time the button is pressed, the display unit 4 automatically displays the second setting state (that is, the display of the remaining cooking time by the subtraction timer). Perform switching operation. Thereby, the display unit 4 determines that the cooking operation is continued in the second setting state, which is an additional operation of the cooking device, without the user performing an operation for switching the display. Automatically display after time has passed. Therefore, the user can always be aware that the cooking operation is continued in the second setting state, and the forgetting that the cooking device is operating in the second setting state can be prevented. . Note that the control unit 7 of the operation unit 3 executes a process for determining whether or not a predetermined time has elapsed since the “temperature up” key 5b or the “temperature down” key 5a was last pressed.

  As described above, according to the present embodiment, the user operates the setting unit corresponding to the setting content that the user desires to change among the first setting unit 5 and the second setting unit 6. Thus, the display on the display unit 4 is automatically switched to the display of the setting state selected by the user. Further, the selected setting state is changed by the user subsequently operating the same setting unit. That is, an operation for selecting a setting state to be set and an operation for changing the setting state can be performed by an operation on the same setting unit. Therefore, the operation area is not moved during the operation, and the user can easily change the setting of the cooking device by the operation that is continued. Therefore, a user-friendly cooking device can be provided. In addition, it is possible to easily grasp the operation of the heating cooker with respect to the operation by changing the notification contents when the display is switched and when the setting is changed.

  Moreover, in the conventional structure, as mentioned above, it was necessary to provide the specific operation means called a selection means in a heating cooker. For this reason, the conventional configuration has a problem that the layout area for the selecting means and the component cost increase. On the other hand, in the present embodiment, each of the first setting unit 5 and the second setting unit 6 has not only a function of changing the setting value but also a function of a selection unit for switching display objects. For this reason, in the present embodiment, it is not necessary to further dispose selection means different from the first and second setting units 5 and 6 in the heating cooker, and the layout region and parts by the arrangement of such selection means. The problem of increased costs does not arise.

  Moreover, in this Embodiment, the area | region where LED4c is arrange | positioned is for displaying the 1st setting state (control temperature of the heating part 1), and simultaneously displaying the 2nd setting state (of the subtraction timer). It is also an area for setting time). Therefore, the configuration of the display unit 4 can be simplified as compared with the conventional case in which a plurality of display areas respectively corresponding to the first and second setting states are individually provided in the display unit. In addition, the area occupied by the region relative to the entire operation unit 3 and the display unit 4 can be reduced, and the size of the entire operation unit 3 and the display unit 4 can be reduced.

  In the present embodiment, the notification unit 2 includes a sound generation source such as a buzzer or a speaker, and performs notification by generating an operation sound. However, the notification unit is not limited to this. For example, the notification unit may be configured by a photodiode, an LED, an LCD, etc., and the notification may be made visually. Or you may comprise a alerting | reporting part by comprising a motor etc. and alert | report by generating a vibration.

  Moreover, in this Embodiment, the example which the 2nd alerting | reporting by the alerting | reporting part 2 was abbreviate | omitted was demonstrated. However, the notification unit 2 may perform a second notification different from the first notification when the display unit 4 switches the display between the display of the first setting state and the display of the second setting state. Good. At this time, the operation sound for the second notification may be different from the operation sound for the first notification. For example, as described above, when the first notification is performed by an operation sound composed of one sound having a length of 0.2 seconds, the second notification is performed by generating a sound of 0.2 seconds. The subsequent stop of the generation of 0.2 second sound may be repeated twice. The second notification may be a sound generation source, a vibration generation source, a light source, or the like as long as it is different from the first notification. Therefore, according to this configuration, it is possible to provide an easy-to-use heating cooker according to the notification mode being different between the switching of the display of the setting contents and the setting change. Note that the notification sound related to the first notification and the notification sound related to the second notification may be the same.

  The first setting is the control temperature setting, and the second setting is the timer setting time. However, the first and second settings are not limited to these, and are other types of setting items. Also good.

  Furthermore, in this Embodiment, the display part 4 is provided with LED4c for performing the display of a 1st setting state and the display of a 2nd setting state. However, for the display of the first setting state and the display of the second setting state, other display means such as an LCD may be provided instead of the LED 4c. In this case, the functions of the LEDs 4a and 4b may be performed by the other display means instead of the LEDs 4a and 4b.

  As described above, the heating cooker according to the present invention can easily display a plurality of operation states while suppressing the expansion of the display area. It can be provided for microwave ovens, hot plates, toasters, etc.
